The effects of temperature on growth, development and settlement of northern rock sole larvae (Lepidopsetta polyxystra)

Creator:: Laurel, Benjamin J., Danley, Courtney, and Haines, Scott
Abstract:: Northern rock sole (Lepidopsetta polyxystra) is a commercially important fish in the North Pacific and a focal species in understanding larval transport to nursery grounds in the Bering Sea. However, the temperature-dependent vital rates and settlement dynamics for this species have not been described in detail. We reared northern rock...

Temperature-dependent growth and behavior of juvenile Arctic cod (Boreogadus saida) and co-occurring North Pacific gadids

Creator:: Laurel, Benjamin J., Spencer, Mara, Iseri, Paul, and Copeman, Louise A.
Abstract:: The thermal sensitivity of Arctic fish species is poorly understood, yet such data are a critical component of forecasting and understanding ecosystem impacts of climate change. In this study, we experimentally measured temperature-dependent growth and routine swim activity in the juvenile stage of two Arctic gadids (Arctic cod, Boreogadus saida...

Effect of temperature and tissue type on fatty acid signatures of two species of North Pacific juvenile gadids: A laboratory feeding study

Creator:: Copeman, Louise A., Laurel, Benjamin J., and Parrish, Christopher C.
Abstract:: The utility of the fatty acid biomarker (FAB) approach in fisheries ecology is limited by our understanding of how biotic and abiotic factors determine dietary markers in fish tissues. An 8-week laboratory experiment was conducted on two species of juvenile gadids (Pacific cod, Gadus macrocephalus and walleye Pollock, Theragra chalcogramma)...

Role of temperature on lipid/fatty acid composition in Pacific cod (Gadus macrocephalus) eggs and unfed larvae

Creator:: Laurel, Benjamin J., Copeman, Louise A., and Parrish, Christopher C.
Abstract:: During early development, oviparous fish species must use finite lipid and fatty acid (FA) reserves for both catabolism and structural components. In cold environments, developing fish have the additional constraint of maintaining membrane fluidity for metabolic efficiency (homeoviscous adaptation), resulting in further demand on lower melting point FAs like n-3...

Ontogenetic patterns and temperature-dependent growth rates in early life stages of Pacific cod (Gadus macrocephalus)

Creator:: Hurst, Thomas P., Laurel, Benjamin J., and Ciannelli, Lorenzo
Abstract:: Pacific cod (Gadus macrocephalus) is an important component of fisheries and food webs in the North Pacific Ocean and Bering Sea. However, vital rates of early life stages of this species have yet to be described in detail. We determined the thermal sensitivity of growth rates of embryos, pref lexion...

Pre-spawning migration of adult Pacific lamprey, Entosphenus tridentatus, in the Willamette River, Oregon, U.S.A.

Creator:: Clemens, Benjamin J., Mesa, Matthew G., Magie, Robert J., Young, Douglas A., and Schreck, Carl B.
Abstract:: We describe the migration distances and timing of the adult Pacific lamprey, Entosphenus tridentatus, in the Willamette River Basin (Oregon, U.S.A.). We conducted aerial surveys to track radio-tagged fish upstream of a major waterfall and hydropower complex en route to spawning areas. We detected 24 out of the 43 fish...

Effects of elevated CO₂ levels on eggs and larvae of a North Pacific flatfish

Creator:: Hurst, Thomas P., Laurel, Benjamin J., Mathis, Jeremy T., and Tobosa, Lauren R.
Abstract:: The Bering Sea and Gulf of Alaska support a number of commercially important flatfish fisheries. These high latitude ecosystems are predicted to be most immediately impacted by ongoing ocean acidification, but the range of responses by commercial fishery species has yet to be fully explored. In this study, we examined...

Maturation characteristics and life-history strategies of the Pacific lamprey, Entosphenus tridentatus

Creator:: Clemens, Benjamin J., van de Wetering, Stan, Sower, Stacia A., and Schreck, Carl B.
Abstract:: Lampreys (Petromyzontiformes) have persisted over millennia and now suffer a recent decline in abundance. Complex life histories may have factored in their persistence; anthropogenic perturbations in their demise. The complexity of life histories of lampreys is not understood, particularly for the anadromous Pacific lamprey, Entosphenus tridentatus Gairdner, 1836. Our goals...

Trace analysis of environmental matrices by large-volume injection and liquid chromatography-mass spectrometry

Creator:: Busetti, Francesco, Backe, Will J., Bendixen, Nina, Maier, Urs, Place, Benjamin, Giger, Walter, and Field, Jennifer A.
Abstract:: The time-honored convention of concentrating aqueous samples by solid-phase extraction (SPE) is being challenged by the increasingly wide spread use of large-volume injection (LVI) liquid chromatography-mass spectrometry (LC-MS) for the determination of traces of polar organic contaminants in environmental samples. Although different LVI approaches have been proposed over the last...
